Abstract：Objective To investigate the risk factors for AHRE after dual-chamber pacemaker im-plantation in elderly patients without history of atrial fibrillation.Methods A retrospective analy-sis was conducted on 159 elderly patients receiving implantation of cardiac dual-chamber pace-makers in the Chinese PLA General Hospital from January 2018 to December 2020.Based on oc-currence of AHRE or not,they were divided into an AHRE group(73 cases)and a non-AHRE group(86 cases).Cox proportional hazards analysis were performed to analyze the survival and risk factors of AHRE.Results Heart failure(HR=2.134,95％CI:1.212-3.758,P=0.009),his-tory of stroke/transient ischemic attack/thromboembolism(HR=2.378,95％CI:1.293-4.375,P=0.005),atrial sensing amplitude＜2.0 mV(HR=2.258,95％CI:1.307-3.900,P=0.004),NT-proBNP＞900 ng/L(HR=1.740,95％CI:1.024-2.955,P=0.040),and eGFR＜60 ml/(min·1.73 m2)(HR=2.118,95％CI:1.227-3.655,P=0.007)were independent risk factors for new-onset AHRE in elderly patients after dual-chamber pacemaker implantation.Conclusion For elderly patients without history of atrial fibrillation after cardiac dual-chamber pacemaker implan-tations,the occurrence of AHRE is significantly associated with multiple risk factors such as heart failure,history of stroke/transient ischemic attack/thromboembolism,eGFR＜60 ml/(min·1.73 m2),atrial sensing amplitude＜2.0 mV,and NT-proBNP＞900 ng/L.
